Growing with erect, branched stems 20 to 120 centimeters tall, it develops a robust and spreading habit. Its leaves are crowded, rigid, and lanceolate to ovate, measuring less than 60 millimeters long, with acute to long-tapered tips that slightly clasp the stem. The small seed capsules are 3 to 7 millimeters long, containing pyramid-shaped seeds with distinct ridges.
